Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaners, specifically a roller brush structure for a vacuum cleaner. Background Technology

[0002] Vacuum cleaners are common cleaning appliances in homes and offices. Current technology typically features a rotating roller brush on the floor brush. This roller brush, combined with suction airflow, efficiently removes dirt and dust from the floor. However, the scraping materials on the roller brush are currently limited, ranging from cleaning cloths to bristles. Each material has its own advantages and disadvantages, failing to simultaneously meet diverse floor cleaning needs and hindering overall cleaning efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a roller brush structure for a vacuum cleaner.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A roller brush structure for a vacuum cleaner includes a roller drivenly connected to the floor brush of the vacuum cleaner and multiple brush strips arranged on the surface of the roller. The brush strips include cleaning bristles and soft scraping strips. The cleaning bristles include a strip-shaped base and cleaning bristles embedded in the strip-shaped base. The soft scraping strips include a strip-shaped scraper and a cloth covering the surface of the strip-shaped scraper. The surface of the roller is provided with multiple slots extending along the roller axis. The cleaning bristles and soft scraping strips are detachably inserted into the slots along the ends of the slots.

[0006] The slots are arranged on the roller in pairs of adjacent ones, and cleaning strips and soft scrapers are respectively installed in the two slots of the pair.

[0007] The slots are arranged in three or more groups.

[0008] The cleaning bristles are positioned in front of the soft scraper, depending on the rotation direction of the roller.

[0009] The slot is a T-shaped slot.

[0010] The slot extends in an arc shape along the axial direction of the roller, and the cleaning bristles or soft scrapers are inserted into the slot in a spiral arrangement.

[0011] The roller is provided with end caps at both ends, and the end caps cover the end slots of the slot.

[0012] The end caps at both ends of the roller are divided into a left end cap and a right end cap.

[0013] The left end cover is provided with an insert seat for inserting into the left port of the roller. The inner wall of the left port of the roller is provided with two or more slots, and the side of the insert seat is provided with a corresponding slot for inserting into the slot.

[0014] The right end cover is provided with a claw for inserting into the right port of the roller. The right port of the roller is provided with a connecting seat. The claw can pass through the through groove on the side of the connecting seat and hook onto the bottom of the connecting seat. The top of the connecting seat is also provided with a screw hole. The end face of the right end cover is provided with a through hole for threading screws.

[0015] The beneficial effects of this utility model are as follows: This utility model arranges multiple composite brush strips on the surface of the roller brush, including cleaning bristles and soft scraper strips. The cleaning bristles are equipped with cleaning bristles, and the soft scraper strips are equipped with strip-shaped scrapers and a cloth covering the scraper strips. The cleaning bristles are responsible for combing the floor or carpet and removing dirt, while the soft scraper strips direct the dirt removed by the cleaning bristles towards the suction port of the floor brush for timely collection and cleaning. The combined use of two different brush strips improves cleaning efficiency. Furthermore, the cloth on the soft scraper strips also provides a wiping effect on the floor, resulting in better cleaning. In addition, both types of brush strips are detachable and replaceable, eliminating the need to discard the entire roller brush, saving significant usage costs, and timely replacement of the brush strips ensures cleaning efficiency.

[0021] Reference Figures 1 to 4A rotary brush structure for a vacuum cleaner includes a roller 2 drivenly connected to a floor brush 1 and multiple brush strips arranged on the surface of the roller 2. The brush strips include cleaning bristles 3 and soft scraper strips 4. The cleaning bristles 3 include a strip-shaped base 31 and cleaning bristles 32 embedded in the base 31, the bristles being stiff. The soft scraper strip 4 includes a strip-shaped scraper 41 and a cloth (not shown) covering the surface of the scraper 41. The scraper 41 provides a scraping motion, while the cloth increases friction and provides a wiping effect on the floor, resulting in better cleaning. When the rotary brush rotates to begin cleaning, the cleaning bristles 3 comb the floor or carpet, removing dirt, while the soft scraper strip 4 directs the dirt combed out by the cleaning bristles 3 towards the vacuum nozzle of the floor brush, collecting and cleaning the dirt promptly. The combined use of these two different brush strips improves cleaning efficiency.

[0022] The surface of the roller 2 is provided with multiple slots 21 extending along the axial direction of the roller 2. The cleaning bristles 3 and the soft scraper 4 are detachably inserted into the slots 21 by sliding along the ends of the slots 21. Both types of brushes can be removed and replaced without discarding the entire roller brush, saving a lot of usage costs. Furthermore, timely replacement of the brushes can ensure cleaning efficiency.

[0023] As a preferred embodiment of this utility model, to better coordinate the two types of brush strips, the slots 21 are arranged in groups of two adjacent strips on the roller 2. Cleaning bristles 3 and soft scraper strips 4 are respectively installed in the two slots 21 of this group. According to the rotation direction of the roller 2, the cleaning bristles 3 are positioned in front of the soft scraper strips 4, allowing the soft scraper strips 4 to promptly remove the dirt after the cleaning bristles 3 comb out the dirt. Considering the cleaning area of ​​the brush strips, at least three groups of the aforementioned slots 21 should be arranged. Similarly, to increase the cleaning area of ​​the brush strips, the slots 21 extend in an arc along the axial direction of the roller 2, so that the cleaning bristles 3 and soft scraper strips 4 are spirally distributed within the slots 21. This increases the contact area between each brush strip and the ground during the rotation of the roller brush, and the spirally distributed brush strips also provide a guiding effect, facilitating the guiding and collection of dirt by the soft scraper strips 4.

[0024] Furthermore, to facilitate the insertion of the brush strips, the slot 21 is designed as a T-shaped groove, and the cleaning bristles 3 and the soft scraper 4 are respectively provided with insertion parts that mate with the T-shaped groove. For example, on the cleaning bristles 3, the widened strip-shaped base plate 31 forms a T-shaped structure with the cleaning bristles 32, which mates with the T-shaped slot 21 for installation. On the soft scraper 4, a horizontally extending locking block 42 is provided at the bottom of the strip-shaped scraper, which also forms a T-shaped structure and mates with the T-shaped slot 21 for installation.

[0025] Preferably, the roller 2 has end caps at both ends, which cover the end openings of the slots 21 to completely limit and fix the brush strip within the slots 21. The end caps at both ends of the roller 2 are a left end cap 5 and a right end cap 6. The left end cap 5 has an insert seat 51 that is inserted into the left port of the roller 2 with an interference fit. The inner wall of the left port of the roller 2 has two or more slots 22. The side of the insert seat 51 has a corresponding locking platform 52 that engages with the slots 22, completely restricting the circumferential rotation of the left end cap 5 relative to the roller 2. The right end cap 6 has a claw 61 that is inserted into the right port of the roller 2. The right port of the roller 2 has a connecting seat 23. The claw 61 passes through the through groove 25 on the side of the connecting seat 23 and can be hooked onto the bottom of the connecting seat 23. The top of the connecting seat 23 also has a screw hole 24, and the end face of the right end cap 6 has a through hole for a screw.
